LIFTING MECHANISM FOR CORN-HARVESTERS.

Patented Nov. 14, 1905.

Original application filed January 19, 1903, Serial No. 139,697. Dividedand this application filed January 18, 1904. Serial No. 189,620.

To all whom it may concern.-

Be it known that I, ARTEMUs N. HADLEY, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Lifting Mechanismfor Corn-Harvesters, of which the following is a specification.

In the operation of that type of corn-harvesters described and claimedin my Patent No. 399,988, issued March 19, 1899, means must be providedto lift the finished shock from the formingtable and deposit the sameupon the ground. In mypending application, Serial No. 139,697, I haveshown a peculiar device for grasping the formed shock and by means ofwhich the formed shock may be lifted from the forming-table andtransferred to the ground.

The object of my present invention is to provide convenient means foraccomplishing the lifting and transferring movements by means of theteam, using in connection therewith such mechanism as is shown inmypending application, Serial No. 118,897.

The present application is a division of my application, Serial No.139,697, referred to above.

The accompanying drawings illustrate the said invention.

Figure 1 is a plan of a machine involving my invention; Fig. 2, asimilar view with the parts in another position, andFig. 3 a sideelevation.

In the drawings, 10 indicates the main body of a machine, upon which isrotatably mounted a horizontal shock-forming table 11. Adjacent table 11is a vertical mast 12, which carries the clamping mechanism 13,described and claimed in the application already referred to. Saidclamping mechanism consists, in part, of a rope 14, the ends of whichare attached to the opposing phalanges of the clamping mechanism, whilea bight is carried over suitable pulleys and around a block 15. Securedto this block is one end of a rope 16, which is carried around a block17 and from thence to a drum 18, mounted upon the main frame of themachine. Drum 18 is mounted upon a suitable shaft 19 and is normallyreturned or rotated backward upon shaft 19 by means of a suitable spring20, said spring serving to draw up the slack of rope 16 and keep block17 at the rear end of the tongue 10 of the main frame of the machine.Drum 18 is provided with a plurality of pins 21 arranged at difierentpoints on its periphery and adapted to be engaged by an arm 22, carriedby a rock-shaft 23. Shaft 23 is connected by a suitable link 24 with ahand-lever 25, arranged close to the seat 26. At a point between drum 18and block 17 rope 16 is provided with a button 27 which cannot passbetween the pulley and casing of the block.

In operation, supposing the shock to have been formed, the operatorstops the machine and disconnects the doubletree, (from the tongue,) sothat it is free to act upon block 17. A pull upon this block pulls bothends of rope 16, button 27 preventing any backward movement of the cablethrough the block, and exerts a pull upon block 15, thus pulling uponcable 14, so as to draw the several phalanges of the clamping apparatus13 together around the bundle in the manner of the movement of the thumband finger of a hand, near to the position shown in Fig. 2. Before theparts can be brought into this position, however, a considerable forceis required, and the operator therefore swings stop 22 into the path ofmovement of the pins 21, thus preventing any further unwinding of rope16 from drum 18. The end of the rope 16 attached to the drum thereu onbecomes immovable, and block 17 is pu ed away from button 27, thusdoubling the effective pull upon block 15.

I claim as my invention- 1. In a lifting mechanism, the combination of apulley-block 17, a cable 16, a drum 18 to which one end of the cable isattached, and a button carried by the cable between the drum and theblock, for the purpose set forth.

2. In a lifting mechanism, the combination of a pulley-block 17 a cable16, a spring-drum 18 to which one end of the cable is attached, a buttoncarried by the cable between the drum and the block, and means forpreventing the rotation of the spring-drum at any desired point.

3. In a lifting mechanism, the combination with a doubled lifting-cableand a pulleyblock in the bight thereof, a movable support for one end ofsaid cable and means for preventing further movement of said support,for the purpose set forth.

4. In a lifting mechanism, the combination with a doubled lifting-cableand a pulleyblock in the bight thereof, a movable support for one end.of said cable, means for preventing further movement of said support,and means carried by the cable between. the pulley-block and the movablesupport, which means cannot pass the pulley-block, for the purpose setforth.

5. In a shock-lifting mechanism a pulleyblock 17, a cable passed throughthe block 17 and secured at one end to a support with slack between theblock and the support, and

means such as a button carried by the slack portion of the cable toprevent it from.pass ing through the block in one direction, for thepurpose set forth.

In Witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 12th day of January, A. D. 1904.
